style="text-indent:25px">橡膠密封圈的經(jīng)密封：可以分為三種情況；往復(fù)運(yùn)動(dòng)一般取W=10%～15%。旋轉(zhuǎn)運(yùn)動(dòng)密封在選取壓縮率時(shí)必須要考慮焦耳熱效應(yīng)，一般來說，旋轉(zhuǎn)運(yùn)動(dòng)用O形圈的內(nèi)徑要比軸徑大3%-5%，外徑的壓縮率W=3%-8%。低摩擦運(yùn)動(dòng)用O型圈，為了減少摩擦阻力，一般均選取較小的壓縮率，遼寧高效橡膠密封件專業(yè)廠家，即W=5%-8%，此外，還要考慮到介質(zhì)和溫度引起的橡膠材料膨脹。通常在給定的壓縮變形之外，允許的較大膨脹率為15%，遼寧高效橡膠密封件專業(yè)廠家，超過這一范圍說明材料選用不合適，應(yīng)改用其他材料的O形圈，或?qū)o定的壓縮變形率予以修正。橡膠O型圈在裝入密封溝槽后，遼寧高效橡膠密封件專業(yè)廠家，一般都有一定的拉伸量。與壓縮率一樣，拉伸量的大小對(duì)O型圈的密封性能和和使用壽命也有很大的影響。拉伸量大不但會(huì)導(dǎo)致O型圈安裝困難，同時(shí)也會(huì)因截面直徑d0發(fā)生變化而使壓縮率降低，以致引起泄漏。橡膠密封件在泄漏和密封這一對(duì)矛盾中扮演十分重要的角色。遼寧高效橡膠密封件專業(yè)廠家</p><div

O型圈采用“外徑×線徑”的標(biāo)記方法，一般稱為老國(guó)標(biāo)； GB3452.1-82與GB3452.1-92基本相同，一般稱為新國(guó)標(biāo)，它規(guī)定的O型圈截面直徑有1.8、2.65、3.55、5.3等，新國(guó)標(biāo)采用國(guó)際慣例，O型圈采用“內(nèi)徑×線徑”的標(biāo)記方法。 O型圈的溝槽設(shè)計(jì)有相關(guān)的國(guó)家標(biāo)準(zhǔn)，主要分動(dòng)密封、軸向靜密封和徑向靜密封三種。O型圈采用軸向壓緊更便于裝配和保證密封性能。另外，我國(guó)國(guó)家標(biāo)準(zhǔn)中的溝槽尺寸標(biāo)準(zhǔn)已顯落后，如國(guó)家標(biāo)準(zhǔn)中受內(nèi)壓的O型圈溝槽外徑等于O型圈外徑，而PARKER法蘭接頭的O型圈溝槽外徑小于O型圈外徑。有O型圈的密封面不得使用平面密封膠，可以在O型圈上涂少量黃油以使其不脫落。在維修時(shí)，應(yīng)根據(jù)溝槽尺寸確定O型圈規(guī)格，并不是線徑越粗越好。遼寧高效橡膠密封件專業(yè)廠家在流體密封中橡膠密封件特別有用。</p><div

style="text-indent:25px">型圈是密封中較常用的一種密封件。但由于選用、溝槽設(shè)計(jì)、加工和裝配上的不當(dāng)，常常造成漏油故障，可謂是小件壞大事。選用O型圈時(shí)，首先應(yīng)盡量選用新國(guó)標(biāo)，線徑2.65和3.55的使用較為普遍，在外徑大于30左右，結(jié)構(gòu)尺寸允許的情況下，盡量選用線徑3.55的O型圈，以達(dá)到更大的壓縮量和接觸面積。圈的材料主要有丁氰橡膠NBR和氟橡膠FKM，氟橡膠更適用于高溫工況。除材料之外，O型圈很重要的一個(gè)指標(biāo)的是它的硬度，一般采用邵氏硬度來表示，從60到90左右不等，數(shù)值越大表示硬度越高。在同樣壓力下，硬度越高，防擠出（變形甚至撕裂）的能力就越強(qiáng)。因此，應(yīng)選用硬度較高的O型圈。但是，市場(chǎng)上常見的O型圈均為丁氰橡膠制成，邵氏硬度一般在70左右，難以滿足相當(dāng)一部分工況的要求。</p><p>

style="text-indent:25px">O形圈橡膠材料的硬度與工作壓力的關(guān)系在橡膠材料標(biāo)準(zhǔn)中，以硬度和壓縮長(zhǎng)久變形兩項(xiàng)性能較為主重。選擇壓縮變形較小的橡膠材料對(duì)密封性能是有利的，而硬度對(duì)于O形橡膠密封圈耐壓和抗擠又是至關(guān)重要的。根據(jù)國(guó)內(nèi)標(biāo)準(zhǔn)和實(shí)踐經(jīng)驗(yàn)，橡膠在規(guī)定溫度下的壓縮長(zhǎng)久變形較大不超過50%。而橡膠的硬度與密封工作壓力密切相關(guān)，壓力越高，硬度也是越高; 橡膠O型圈模壓制品在硫化時(shí)，膠料會(huì)很快充滿整個(gè)模腔，因?yàn)樘畛涞哪z料需要一定的過盈量，這些多余的膠料就會(huì)沿著分模面流出，造成內(nèi)外徑不同厚度的膠邊。由于橡膠O型圈是需要嚴(yán)格控制質(zhì)量和外觀的，因?yàn)槠涔δ転槊芊?，小小的膠邊就有可能影響到整個(gè)密封性能，所以硫化后的成品還需要進(jìn)行修邊加工，要對(duì)這些多余的膠邊進(jìn)行去除工作，這個(gè)過程就叫做修邊。但是一般來說尺寸規(guī)格越小，構(gòu)型越復(fù)雜，難度越高，費(fèi)時(shí)耗工越多。橡膠可分為硬膠和軟膠，生膠和混煉膠。北京耐酸堿橡膠密封件供應(yīng)廠家</p><p
